My removable retainer has fractured
If a small part of the acrylic (plastic) has come away, you should try to continue to wear the retainer if it is possible. If the retainer is broken into lots of small pieces, do not wear it. If it is cracked into two large parts, it can often still be worn but you should still contact the practice for advice.
If the fractured area is excessively sharp, you can use an emery board or nail file to smooth the sharp area. If you are unsure, you should contact the practice.
Depending on where the fracture has occurred and how much has come away, we may have to see you sooner. Contact the practice for advice, and if necessary, an earlier appointment.
